You may also see a "Protocol Violation error, the thin driver throws this exception when it reads something from the RDBMS that it did not expect. This means that the protocol engine in the Thin driver and the protocol engine in the RDBMS are out of synch. There is no way to recover from this error. The connection is dead and You should try to close it, but that will probably fail too.
If you are able to reproduce the error, please file a TAR with Oracle Global Support by specifying the exact version numbers of the JDBC driver and the RDBMS.

Possible Solution:
It is very hard to troubleshoot and the simplest solution is to upgrade your JDBC Driver.
This exception no longer occurs in JDBC 11.2.
